Application fried February my iiivention is to which tlie contour of ofthe tufts may be my invention is to provide for the ready .renioval ofany of the self-contained groups of tufts aiid the replacement thereofafter wear to groups possessing Still another objec whereby the groupsranged or a. change a different quality.

t is to provide a means of. tufts may be arin other than an unbrokenline for tlie purpose of avoiding obstacles. Still further objects of myinvention are to provide a device for tlie purpose aintended which is sirugged, easy to oper get out of order.

In the drawings, a by way of example, bodiments of the inv Fig. l is aside View inple to manufacture, ate and which will not cconipanying, isshown, one of tlie possible emention:

of the device showing tlie tufts grouped to form a concave coiitour.

such as aluiniiium,

with a tubular end portion 2, v'fiattened and widened, if required, atthe brush end of the handle.

Mounted on the said brusliend 2 are channels 3 with inwardly bent edgesor legs ,4. Tlie said channels are secured,

through openings 5, disks or wlieels 6, a toothed idler 7.

secured in ak composition, such as celluloid. inserts snugly into andthrough being held therein frictionally,

ing providedfon the top edge of every side with-a recess whereby toengage a corresponding projection, selectively placed oii sides 4 ofchannell.

VVhen used asa tooth brush, it is obvious that the brushes may bearranged to clean the outside ofthe teeth (Fig. 1); to clean the inside(Fig. 3); or, as in (Fig. 2) to cleanse the outer and inner parts of aplate for artificial teeth.

VVhile a specific application of the inveiition is herein described, theinvention is not limited to this since the device may be adapted to manyand various uses without departing from the scope of the invention, asclaimed. i

I claini: i

1. The combination of a handle having an end portion providing asupporting means, a pair of members rotatably mounted on said endportion, each member being provided with a row of bristle tufts, saidtufts being graduated in lengths from one end to the other of the memberwhereby said member inay be rotated to effect a brushing surfaceofconcave or convex contour.

2. A tooth brush consisting of a handle Vflattened and liollowed, a pairof toothed dislrsspaced apart in said hollow portion, a toothedidlerdisposed in saidV lliollowportioii between the ldisks and engagingboth the disks, mounts attached to said disks for rotationtherewith. andmeans on each of thereon eiid for end, each member carrying` a row ofbristles graduated from end to end thereby forming deep, and shallowends, whereby when the shallow endsare adjacent a yconcaved "biushingsurface is formed and when the deep endsare adjacent a conveXed brushingsurface is formed.
